Application filer. January 12. 1907- Serial No, 351856;

To all whom it may camera:

Be it known that I, RALPHL. MoRoAN, a citizen of the United States, residing at l forcester, in the county of Worcester and State of Massachusetts, have invented a new and .useiul Wheel-Rim Fastener, of which the following is a specification.

This invention relates to that class of wheels in which a detachable rim is placed on the rim mounted on the folly, said detachable rim having inwardly turned side flanges or the like for holding a clencher tire,

the tire and detachable rim being remov able together as a whole.

The principal objects of theinvcntion are to provide for securely fastening the detachable rim in place in such manner that there will benodetachable small parts and no bolts will have to be passed through or into the felly for this purpose, thereby avoiding the weakening of the folly by the bolt holes and especially avoiding the necessity of unscrewing or otherwise detachlng any removable holding device or devices when'the removable rim is to be taken off; also to provide" a simple and convenientfastening device which will hold the parts securely in position and will require no adjustment of separable holding or fastening means in order to rc 'nove the rim, and which will hold securely even if the parts should become deranged in use, furthermore to provide a very simple means in the form of a continuous unsplii ring for securing the clamping action I directly between the fixed rim and the delzur lzllilf rim.

liurtlwr objects and advantages of the invention will appear hereii'iafter.

Reference is to be had to the accompanying SllOUlnOf drawings .in which,

Figure 1 represents a perspective sectional view of a portion of a wheel tire exhibiting a preferred embodiment of this invention. 1 1g. 2 is a fragmentary perspective view showing a preferred form of clamping or locking ring therefor, and Fig. o similar to Fig. 3 showing a part of the fixed The invention is carried out by so locating a fastening ring that it Wlll bear on adjacent but oppositely facing surfaces on the fixedis a View l face I) which preferably is slanting so that the detachable rim 0 which is provided with a corresponding surface 0 can be wedged thereon. The detachable rim 0 is provided with a lair of inwardly turned side'ilanges 0 preferably fixed or integral with respect thereto for the purpose of holding a clen-cher tire d of any desired character.

The rim 0 with. the tire thereon is intended to be, placed on the rim 6 by forcing it over the same the surfaces 1) and 0 coming into contact with each other.

For the purpose of bringing the removable rim 0 to proper position and securely clampthe above mentioned results, the rim 7) ac cording to this invention is rovided with a flange b which is preferab y integral with the rim. ward the center of the wheel from the rim 1) and inay be spaced at some-little distance from the edge of the telly. It has a slanting outer surface I) for the purpose of affording a wedging action as will be described. The'detachable rini c has an oppositely slanting surface 0 A circular fastening rim 6 is provided for the purpose of engaging the surfaces 6 and c and means is provided for drawing the ring inwardly to force these surfaces a art and clamp the rims together when t e ring is turned in one direction. The ring e is of wedge-shaped form in cross section, and forms a complete circle. It is provided with clamping means shown in the 'orm of a series of wedge shaped lugs e adapted to engage lugs b. shown on the fixed rim. The ring is placed in position with the .lugs engaging eac 1 other and turned on its axis in any desired way, as for example by striking lugs c with a hammer or the like. This securely locks the detachable rim 0 directly to the fixed rim 1), and it will be seen ing devices, such as bolts, whereby the above mentioned results are obtained.

The ring can readily be unlocked without manipulation of a single holding or fastening device merely by striking the lugs e in the other direction. The operation of placing the ring in place and forcing it to a position gether, will be obvious. By the use of a fastening ring, any derangement which may be caused by the yielding, or even bending, of the flange or by Wear, is compensated for in tightening up the ring. i

This flange pro ects inwardly tothat it does away with all detachable fastenk ing it in place in such a manner as to secure in which it will securely hold the rimsto- It will be seen that by the construction of a wheel in accordance with the'principle of this invention, whether in the exact form illustrated or otherwise, the detachable rim can be most uickly clam ed in position on 1 the wheel, wit any desire amount of wedg-,

ing action, and'when it is desired to dismount it, it can as readily be detached without the necessityof unfastening any fastening devices except the ring itself. Moreover, the clampmg action is secured in a s1m-' glre and-inexpenslve manner w1thout modiing the felly of the wheel in any way, and

without weakening the same by making bolt holes therethrough, and there are no detachable small arts that can be lost or broken.

The mo ification' in the construction of the fixed rim 6 is of'such a simple character that it does not materially add to the ex pen'se of this part of the device. a

While'I have illustrated anddescribed one form in which the invention can be embodied, I am aware that modifications may be made therein, both in the fastening ring itself, and in the means for holding the same as well as the other parts of the device, Without departing from the spirit of the invention as expressed in the claims. Therefore I do not wish to be limited tothe particular construction of features shown, but

.VVhat I'do claim and desire to Letters Patent is z- 1. The combination with. an inner wheel rim having an elevated bearing surface, ofan outer rim bearing near one side on said elevated surface, and a fastening device supporting the other side of the outer rim from the inner'rim, said inner rim having means located between the rims and entirely at one side thereof for clampingthe fastening device thereto.

'2. The combination with a Wheel rim havsecure by v ing a bearing surfacelnear one side and a flange near the other, of a detachable rim adlafpted to rest at one edge on said bearing su ace, anda wedge-shaped'ndless fasten-f an endless wedge -,shapedfastening ring adapted to enter a space between the rims 1 and support one from the other, said fixed rimhaving a series of wedge-shaped lugs on its outer surface and said ring having corresponding inwardly extending wedge-shaped lugs ada ted to engage the first named lugs to hold t 1e ring in position, whereby the ring will conceal the lugs. r

4-. In a fasteningdevice for a wheel rim, an endless rinwedge-shapedin cross-section, with the arrow edge of the wedge extending substantially perpendicularto ,the plane of the wheel, said ring having fastening devices on the inner surface thereof, ada ted to be entirely concealed-and rotected y the ring when in position, an being rovided with lugs on t 1e opposite outer su ace for receiving blowsfor forcing the same into "fastening position.

Intestimon whereof I have hereunto set my hand, in t e presence of two subscribing witnesses. 1 t I I AL H L. MORGAN.
